This paper presents general relativistic numerical simulations of uniformly rotating polytropes. Equations are developed using MSQI coordinates, but taking a logarithm of the radial coordinate. The result is relatively simple elliptical differential equations. Due to the logarithmic scale, we can resolve solutions with near-singular mass distributions near their center, while the solution domain extends...
We present simulation and experimental results of a hybrid plasmonic/dielectric waveguide with a grating, which efficiently converts radiation to surface plasmons. Resonant cavities yield energy density enhancements of 225 times the incident energy density.
Surface plasmon polaritons?? (SPPs) and composite diffracted evanescent waves?? (CDEWs) role in enhanced optical transmission are reviewed experimentally, via numerical modeling, and theoretically. All results support involvement of SPPs and contradict the existence of CDEWs.
